The answer is C. Habsburg Empire
Answer:
1. b) The incorporation of the 14th Amendment has consolidated power between the government at the local, state, and federal level.
2. a) The Supreme Court overturned the separate but equal doctrine in schools.
Explanation:
1. The 14th Amendment's incorporation concentrates local, state, and federal power. Section 1 of this amendment states, "No state shall abridge the rights or immunities of U.S. citizens; nor shall any state deprive any person of life, liberty, or property without due process of law; nor shall any state deny any person within its jurisdiction equal protection of the laws."
2. Brown v. Board of Education of Topeka abolished the 1896 Plessy v. Ferguson tenet of "separate but equal" in schools. This judgement did not say that separating pupils by race was intrinsically improper; rather, it declared that if two schools were really equal, they should be permitted to separate without legal repercussions.
It's somewhat a matter of opinion, since many people have their favorites and it always looks good if you answer "Nelson Mandela". The truth is that after WW 2, the world got divided into a "Western" bloc under US leadership and a Communist bloc under the Soviet Union. The various US Presidents and Communist Party Secretaries all shaped the world in the Cold War era. A good candidate however is Soviet party leader Mikhail Gorbatchev, who practically single-handedly dismantled the old Soviet Union and thereby ended Communist rule over many eastern European countries. Americans tend to thank Ronald Reagan for that, but that is vastly overrating his actual influence on affairs. We Westerners like Gorbatchev for that, but in Russia he is generally seen as a weak leader and the man who 'sold out' Russia's global power and prestige and who was responsible for much of the following unrest until "thank God" Vladimir Putin took firm control and put Russia back on the map again.
